----------------------------------------
TestNG discussion thread:
https://groups.google.com/forum/#!topic/testng-users/MkqmrrKDsVg
As for properties, if I'm reading it right I changed the POM to be:
{code:title=POM.XML snippet}
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.18.1</version>
<configuration>
<properties>
<property>
<name>parallel</name>
<value>methods</value>
</property>
<property>
<name>dataproviderthreadcount</name>
<value>13</value>
</property>
</properties>
</configuration>
</plugin>
{code}
This is causing the following exception:
{code:title=Stack Trace}

> Key: SUREFIRE-1179

> Project: Maven Surefire
> Issue Type: Bug
> Components: TestNG support
> Affects Versions: 2.18.1
> Environment: Windows 7 x64, Java 8 (1.8.0_60), TestNG v6.9.6, Maven
> Surefire version 2.18.1
> Reporter: Jeff Vincent

> Attachments: testng-test.zip

> I have some simple tests I'm trying to configure to run in parallel using
> Maven 3.3.3 and the latest versions of TestNG. I've set my POM file to the
> following:
> <plugin>
> <groupId>org.apache.maven.plugins</groupId>
> <artifactId>maven-surefire-plugin</artifactId>
> <version>2.18.1</version>
> <configuration>
> <parallel>methods</parallel>
> <threadCount>50</threadCount>
> </configuration>
> </plugin>
> When I run in parallel, I only get 10 threads no matter the setting and I can
> not change it. I've tried adding the annotation parameter to the method as
> well:
> @Test(dataProvider = "dataProvider", threadPoolSize = 50)
> Nothing seems to help. I have a simple project that illustrates what I'm
> seeing.
